[0026] The embodiments of the utility model will be described in detail below in combination with the drawings.
[0027] Embodiment: as Figures 1 to 7The illustrated is a support for large cantilever cap beam construction, the main purpose is to support the mold for making large cantilever cap beam 2, the mold includes bottom die 8 and end die 9, and then the large cantilever cap beam 2 is formed by pouring in the bottom die 8 and the end die 9. In the prior art, in order to meet the structural stress requirement when manufacturing the large cantilever cap beam, the construction support is usually adopted. After the construction is completed, the steel pipe pile is not easy to pull out, which causes the waste of steel pipe pile material and increases the construction cost, and the economy is not good. In order to solve the above technical problems, the construction support in the embodiment is arranged based on the tie beam 1, the tie beam 1 is used to connect the pier column 3 and has a support expansion part 1-1 for supporting the construction support. The construction support mainly consists of support columns 4, cap beam supports 5 and bottom die side supports 6. In the construction process, the support columns 4 do not need to be pre-buried in the soil and can be directly installed at the support expansion part 1-1 of the tie beam 1. The pile head part is enlarged, that is, the support expansion part 1-1 is arranged, and the support clamp 10 is tightly held on the pier column 3 and falls on the support expansion part 1-1. The support columns 4 are located on the side of the pier column 3 for supporting the cap beam supports 5, and the number of the support columns 4 can be set as required. The lower end of the support column 4 can be fixed on the pier column 3 through the support clamp 10, which can be removed later. In this process, the support clamp 10 can fix the support column 4 on the pier column 3, and on the other hand, because the contact area of the support clamp 10 with the support expansion part 1-1 is larger than the cross-sectional area of the support column 4 with the support expansion part 1-1, the stability of the support column 4 in the installation and use process can be ensured, and the structural strength of the whole construction support is enhanced.
[0028] The cap beam supports 5 are used to support the bottom die 8, and the bottom die side supports 6 are installed between the bottom die 8 and the cap beam supports 5 for supporting the position of the bottom die 8 close to the end die 9, so as to ensure the stability of the bottom die 8 and the end die 9 in the installation and use process, and reduce the manufacturing difficulty of the large cantilever cap beam 2.
[0029] The height of the pier column 3 is determined by different bridge structure forms. In order to ensure the stability and structural strength of the support column 4 in the whole supporting process, the support column 4 is fixed on the side of the pier column 3 through the fastener one 7 at the position above the support clamp 10. In order to facilitate disassembly and reduce the disassembly difficulty, the fastener one 7 is a column clamp. The specific number of the column clamp can be designed according to the height of the pier column 3.
[0030] In order to facilitate assembly, reduce the difficulty of production, the above-mentioned cap beam support 5 is composed of an assembled truss 5-1 and a connecting rod 5-2, a plurality of the above-mentioned connecting rods 5-2 are connected between the two groups of the above-mentioned assembled trusses 5-1, and the two groups of the above-mentioned assembled trusses 5-1 are arranged in parallel with each other. The spacing between the two groups of the above-mentioned assembled trusses 5-1 is adapted to the size of the large cantilever cap beam 2, and the main purpose is to support the bottom die 8 and the end die 9 located thereon. The above-mentioned assembled truss 5-1 includes a side truss 5-1-1 and a middle truss 5-1-2, the above-mentioned side truss 5-1-1 is two, and the two above-mentioned side trusses 5-1-1 are located on the side edges of a plurality of the above-mentioned middle trusses 5-1-2, the above-mentioned side truss 5-1-1 and the above-mentioned middle truss 5-1-2, the above-mentioned middle truss 5-1-2 and the above-mentioned middle truss 5-1-2, and the above-mentioned middle truss 5-1-2 and the above-mentioned side truss 5-1-1 are connected by bolt connection or other detachable connection, which facilitates assembly, reduces the difficulty of production, and thus reduces the production cost. The above-mentioned side truss 5-1-1 is triangular, and the above-mentioned middle truss 5-1-2 is square. The side truss 5-1-1 and the middle truss 5-1-2 both have upper horizontal rods, lower horizontal rods, and web rods connected between the upper horizontal rods and the lower horizontal rods, etc., to ensure the structural strength of the whole construction support. The single group of the above-mentioned assembled truss 5-1 in the embodiment is a symmetrical body, which is composed of four parts, i.e. two side trusses 5-1-1 and two middle trusses 5-1-2. The detachable connection facilitates transportation, and because the weight of a single component is relatively light compared to the whole, it is convenient for hoisting tools to hoist and assemble the component, so that the lifting lugs can also be arranged on the top of the above-mentioned side truss 5-1-1 and the above-mentioned middle truss 5-1-2 or other positions.
[0031] The side edges of the above-mentioned bottom die side support 6 are provided with platform supports 11 with footboards 12, which facilitate the standing of construction personnel. In order to ensure the structural strength and stability of the whole platform support 11, the above-mentioned platform support 11 is arranged in a triangular shape.
[0032] The above-mentioned cap beam support 5 and the above-mentioned support column 4 are provided with a dismounting block 13.
[0033] The construction support for large cantilever cap beam in the embodiment has a clever structure and is easy to disassemble. By arranging the tie beam 1 in the shape of a support expansion part 1-1, the support column 4 in the construction support can be directly supported at the support expansion part 1-1. Compared with the traditional cap beam support using soil steel pipe piles, there is no technical problem of pulling out the steel pipe piles, and there is no waste of steel pipe piles, thereby saving construction cost and facilitating the popularization and application of the construction support for large cantilever cap beam in the field of bridge construction technology.
